MACHINE FOR DRILLING BOOKS Patented Jan. 29, 1913..

Original application filed January 16, 1917. Serial No. 142,627. Divided and this application filed May 4, 1917. Serial No. 166,336.

To all whom it may concern:

Be it known that l, Gnouon B. DRAGI-i, a citizen of the United States, residing in the city of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Machines for Drilling Books; and I do hereby declare that the following is a full, clear, and exact description thereof. which, in connection with the drawings forming a part of this specification, will enable others skilled in the art to which my inventions relate to make, use, and practise the same.

My invention relates generally to a ma chine for employing the method of drilling bocl forming the subject-matter of my application Serial Number 1 12,627, filed January 16, 1917, of which this is a division, and particularly to improvements in book drilling machines for piercing books such as telephone directories and the like, so that a hanger cord may be inserted through a corner thereof.

The object of my invention is to accomplish the boring or drilling of books at relatively the same point in each, and so that the hole produced shall be uniform not only throughout the book but also at the sides, and particularly at the side where the drill leaves the book in piercing it, so that splitting or tearing of the paper about the edge of the bore may be avoided. 7

My object is also the provision of a machine by which such mcthod described may be practised and which shall be automatic in its operation, and which shall be capable of operation at high speed.

My invention further consists in novel features of construction and operation of a drilling machine, as will hereinafter be fully described, together with the best form thereof now known to me for attaining the pan ticular features of novelty and utility characterizing my inventions.

In the accompanying drawings, Figure 1 is a side elevation of the machine; Fig. 2 is a plan view; Fig. 3 is a detailed view showing adjusting means adapted for feeding books of different thickness from those shown in Figs. 1 and 2; Fig. 4 is a frag mentary plan View of the means for feeding); books of the thickness for which the adjust ment shown in Fig. 3 is adapted; Fig. 0 an end View of the machine; Fig. 6 is a plan secured to a rod 18.

view of a portion of the machine showing the parts in a different position from that shown in Fig. 2; Fig. 7 is a diagram representing the cycle of operations of the machine.

Referring to the drawings in detail, a driving shaft 1 is journalcd in bearings 2 forming part of the mainframe 3. Secured to the driving shaft is a worm 1 in mesh with a worm wheel 5 which is secured to a shaft 6. Secured to shaft 6 is a cam 7 having a cam groove 8 in which travels a roller 9 journalcd on the bar 10. One end of the bar'lO is provided with a slot 11 so that it will ride on the shaft 6. The other end of the bar is connected to an arm 12 which is secured to a shaft 13. Secured to shaft 13 is an arm 14: having rollers 15 journaled on its outer end. Rollers 15 travel in an annular groove 16 formed in a collar 17 which is To one end of rod 18 attached a drill 19. The rod 18 is provided with a slot 20 which is engaged by pins 21 projecting inwardly from a sleeve 22, which surrounds the rod 18. T he end of the sleeve 22 is provided with portions 23 of smaller diameter, which are free to rotate in bearings 24. Forming part of leeve 22 is a helical spur pinion meshing with the helical spur gear teeth 26 formed on a wheel 27 which is secured to the driving shaft 1. Secured to shaft 6 is a wheel 28 which is pro vided with a cam groove 29, in which travels a roller 30 journaled on a bar 31. One end of bar 31 is provided with a slot 32 so that it will ride on the shaft 6. The other end f the bar 31 is connected to an arm 33 which. is secured to a shaft 34:. Secured to shaft 34 is an arm-35 which is connected by a link 36 to a plunger 37 having a reciprocating movement in guides 38. Pivoted on the plunger 37 is a pawl 39 adapted for engagement with teeth 40 of a ratchet wheel which is secured to a shaft 41. To shaft 41 are secured chain wheels 42 (see Fig. 2) over which travel chains 43 traveling over chain wheels 14 which are secured to a shaft 45. The chains travel at a slightly higher level than the upper side of a table 46, so that when a group or stack of books 47 are transferred from a trimming machine and placed upon the table 1-6, such of the group as rest upon the chains will be supported by the chains 7 are so placed as to stand side by side upon edge in a horizontal row, which row is to be regarded as composed of such number of separate stacks or groups of books as is determined by the thickness of each unit. The books resting upon the chains pass between side guides 48 and a side guide d9 located at a height greater than the guides 18. The action of the part 7 or cam groove 29 on roller 30 of bar 31 and parts connected therewith causes the forward movement of'the plunger 37 and the consequent movement of the chains 13, thereby causing the forward movement of the books 47. The forward movement of the books causes one of said books (6 and the plunger 37 to press the pre ceding boo-ks c and 5 forward between guides 50 and 51 forming part of a channel which is offset and permits the books to be shifted laterally from the channel formed by guides 48. At the end of the forward movement of the plunger 37 the book I) is forced against an anvil 52 through which passes the drill 19 attached to the rod'lS. During the time that the part 9 of cam groove 29 causes the plunger 37 to clamp the books c?" and Z) against the anvil 52, the part it of cam groove 8, as shown in Figs. 1 and 7, will cause forward movement of the drill 19, thereby causing a hole 53 to be drilled through book 7), and a hole 5 1 to be drilled halfway through the book 0. During the time the part 1 of cam groove 8 causes return movement of the drill 19, the part of cam groove 29 will cause return movement of the plunger 37, thereby causing the books 0 and 7) to be released. Secured to the shaft (3 is a wheel 55 having a cam groove 56 in which travels a roller 57 journaled on a lever 58which is pivoted at 59. The free end of lever 58 is connected by .a link 60 to one end of a lever. 61 which is pivoted at 62. The other endof lever 61 is connected to a planger-.63 which is connected to an arm 61 pivoted at (35. Lever 58 is also connected by a link 66 to one end'of a lever 67 which is pivoted at 68. The other end of lever 67 is connected to a bar 69 which is connected to an arm 70 pivoted at 71. Pivoted to the bar (59. is a pivoted plunger72. The plunger72 is'provided with an arm 7 3 which is connected to the bar 69 by means of a spring71. During the time that part 7: of cam groove 8 causes the drill 19 to remain in the back position,'the part Z of cam groove 56 acting on arol'ler 57 of lever 58 and parts connected thereto, causes movement of the plungers 63 and 72 from the position shown in Fig. 2 to the position shown'in Fig. 6. The movement ofplunger 68 causes the book Z) to be moved against an inclined guide 75 which serves to force one end of the book slightly forward, the book at the end of movement of the plunger 63 being in alinement with a channel formed by side guides 76 and 77, the

movement of the plunger 72 at the same time causing the outer end of the plunger to be. moved behind the book (Z succeeding the. book 0. The part we of cam groove 56 will then cause return movement of the plungers G3 and 72, whereby the plunger 63 is moved clear of the book 0, and plunger 72 forces book d over against an incline 78 forming part of the side guides 19 and 51, whereby one end of the book is moved slightly forward. At the end of movement of the plunger 72, the book (i will be moved into range with the channel formed by the side guides 50 and 51 and to rest in front of the plunger 37. Then as the part f of cam groove 25) -auses movement of the plunger, the book (I and book (2 will be forced forward against the anvil 52 in a manner similar to that previously described with reference to the forward movement of the books 0 and 7). At the same time movement of the books (Z and c will cause moven'ient. of the book 7) forward between the guides 76 and 77. The book I) will then occupy the position shown by book in Fig. W'hen forward movement of the plunger 37 by means of pawl 39 causes iotation of the shaft -l1, a chain wheel 75) secured to the shaft 11 causes movement of a chain 80 traveling over a chain wheel 81 which is secured to a shaft 82. Secured to shaft 82 are chain wheels 83, over which travel chains 84 traveling over chain wheels which are secured to a shaft- 86. During the lateral movement of the books 0 and 7) they are supported by the table -16 and not by the chains 18 or chains 81-. but when the books are moved to the position shown by book a, they travel up onto the chains Slwhich are placed at a higher level than the table 46. As shown in Figs. 1, 2 and G. the machine is adjusted for feeding and boring thick books.

By reference to Fig. 2 it; will be seen that the hole that has been drilled extends entirely through one book and part. way through a second book. \Vhen the plunger (33 moves the book I) away from the anvil 52. and the plunger 37 causes the book 0 to be moved up against the anvil, it will be seen that the hole 51 extending part way through the book is then forced against the anvil. This hole receives the advancing drill as it is fed forward. and any marring of the case or cover of the book is avoided, the hole serving also as a drill locator. The last semi-drilled unit of each series is thus advanced to become the first of the succeeding series. When it is desired to feed and bore thin books. the adjustments shown in Figs. 3 and 4 are made. so that the drill, when moved forward, will drill through two thin books and part way through a third thin book. The space occupied by the three books shown in Fig. l is greater than that occupied by the two books shown in Fig. 2.

Therefore, the plunger 37 musthave a longer stroke, which is accomplished by dis connecting the bar 31 from the arm 33 and Connecting it to an arm 87 which is secured to the shaft 34, whereby space is provided for two thin books to be moved between the incline 78 of the guide 49 and a thin book having the hole 54 bored part way through. The guide 49 is also adjustable to provide for more space, the adjustment being accomplished by releasing clamping bolts 88 passing through a slot 89 formed in the side guide 51 of which the guide 49 forms a part, the guide 49 being secured. in place by means of the clamping bolts 88.
